create

path - The path of the created ITuple. The path can either be a relative or full path.
("/folder1/folder2/dataName" and "../folder/dataName" are valid paths).
All the directories in the path must exist. The characther `/` cannot be used
in names; it is only used to delimit directories within paths.

title - The title of the n-tuple

columnNames - The names of the columns

columnType - The types of the columns
Options string must consist of series of parameters or key-value
pairs that are separated by comma or semicolon ( "," or ";" ), white spaces are
disregarded and will be trimmed away during parsing. Key-value pairs must be in a form:
key=value, or key="value" (for values that contain spaces, commas, or other special
characters). Single parameters may be converted to a parameter=true pair during parsing,
like "verbose" -> "verbose=true". Any key that starts with "annotation." will be stripped
of this prefix and put into annotation of newly created AIDA object.

createChained

Creates a logical chain of ITuples. All ITuples in the set must
have the same structure. Chained ITuple can not be filled.
Original n-tuple data is not copied.

Parameters:

path - The path of the chained ITuple. The path can either be a relative or full path.
("/folder1/folder2/dataName" and "../folder/dataName" are valid paths).
All the directories in the path must exist. The characther `/` cannot be used
in names; it is only used to delimit directories within paths.

createChained

Creates a logical chain of ITuples. All ITuples in the set must
have the same structure. Chained ITuple can not be filled.
Original n-tuple data is not copied.

Parameters:

path - The path of the chained ITuple. The path can either be a relative or full path.
("/folder1/folder2/dataName" and "../folder/dataName" are valid paths).
All the directories in the path must exist. The characther `/` cannot be used
in names; it is only used to delimit directories within paths.

createCopy

path - The path of the resulting ITuple. The path can either be a relative or full path.
("/folder1/folder2/dataName" and "../folder/dataName" are valid paths).
All the directories in the path must exist. The characther `/` cannot be used
in names; it is only used to delimit directories within paths.

createFiltered

Creates a new reduced tuple (less rows) from an existing one
by applying a filter. Data is explicitly copied to a new n-tuple.

Parameters:

path - The path of the filtered ITuple. The path can either be a relative or full path.
("/folder1/folder2/dataName" and "../folder/dataName" are valid paths).
All the directories in the path must exist. The characther `/` cannot be used
in names; it is only used to delimit directories within paths.

createFiltered

Creates a new reduced tuple (less rows) from an existing one
by applying a filter. Only subset of the variables (columns) is copied.
Data is explicitly copied to a new n-tuple.

Parameters:

path - The path of the filtered ITuple. The path can either be a relative or full path.
("/folder1/folder2/dataName" and "../folder/dataName" are valid paths).
All the directories in the path must exist. The characther `/` cannot be used
in names; it is only used to delimit directories within paths.

createEvaluator

expression - String defining of the evaluator expression.
This expression is composed by matematical functions and column names.
If the tuple has a folder like structure, inner columns are specified by using the dot "." to represent the folder.
For example let's consider a tuple with the following structure: "{float a; f1={double px,py,pz; ff1={E}}; f2={double x,y,z} }".
Inner columns are represented as:
- "f1.px"
- "f1.ff1.E"
- "f2.x"
Operations among columns are allowed only in the following two cases:
- the columns are at the same level: "f1.px + f1.py"
- the columns are nested in each other. In this case the loop is done on the innermost column:
"a + f1.px" (loop done over "f1.px")
Operations among other types of columns are not allowed.
For example "f1.px + f2.x" is not a valid expression as it is not garanteed that the two folders have the same number of entries.
If the user desires to perform such an operation it will be necessary to loop over the tuple by hand.
